Mental and psychological trauma is traditionally viewed as tragic and unequivocally damaging.

A new philosophical view of suffering shows that trauma, however terrible, may have distinct benefits.

Researchers at Tel Aviv University have discovered that individuals with Holocaust-survivor parents may be less likely to suffer from post-traumatic stress disorder in the wake of their own traumas.

In a study published in the Journal of Traumatic Stress, the researchers set out to see if so-called second-generation Holocaust survivors also undergo more post-traumatic “growth.”

“Post-traumatic growth can be defined as a workable coping mechanism, a way of making and finding meaning involved in the building of a more positive self-image and the perception of personal strength,” said psychologist Dr. Sharon Dekel.

“We were interested in studying the effect of the Holocaust on the second generation’s propensity for this kind of growth. If we can identify verifiably positive implications of trauma, we will be able to incorporate them into treatment and teach people how to grow after terrible experiences,” she said.

Investigators have often focused on the negative implications of trauma as children of survivors often bear a burden from their parent’s abuse. But a growing body of evidence suggests that trauma can have positive outcomes as well.

Some survivors of traumatic events develop new priorities, closer relationships, an increased appreciation of life, a greater sense of personal strength, and experience heightened spirituality.

In an earlier study, Dekel and Zahava Solomon found that veterans of Israel’s Yom Kippur War were less likely to experience post-traumatic stress disorder (PTSD) and related conditions many years after combat if they were also second-generation Holocaust survivors.

The researchers proposed several explanations, including that children of trauma survivors may have acquired coping mechanisms from their parents that helped protect them from traumas in their own lives.

With this theory in mind, they returned to combat veterans of the Yom Kippur War for their latest study. Using self-report questionnaires, the researchers assessed post-traumatic growth in the veterans 30 and 35 years after the war.

The second-generation Holocaust survivors, therefore, don’t experience their own traumas as “trauma virgins” would, since they are already conditioned by their parents’ experience — and, therefore, themselves experience no growth.

Dekel and Solomon offer several explanations for the fact that second-generation Holocaust survivors who fought in the Yom Kippur War apparently do not have higher rates of post-traumatic growth to match their lower rates of PTSD.

The second-generation Holocaust survivors could have grown up in families that did not discuss trauma, inhibiting their post-traumatic growth.

Moreover, they could have inherited their parents’ guilt for having survived the Holocaust, making it difficult for them to associate trauma with growth and causing them to underreport post-traumatic growth in the latest study.

Another proposed explanation is that second-generation Holocaust survivors grew up constantly exposed to their parents’ trauma, making war less stressful for them and lessening their post-traumatic growth, which is understood as the result of struggle with the trauma.

The researchers dismiss the idea that no trans-generational transmission of trauma occurs at all, noting that both their studies on the subject show that second-generation Holocaust survivors respond differently to trauma than others.

Future research will focus on identifying objective markers of post-traumatic growth in trauma survivors and their children, looking at things like stress-hormone levels, open-ended narrative descriptions, and reports by friends, said Dekel.
